COMPUTER - VON NEUMANN ARCHITECTURE

VON NEUMANN ARCHITECTURE

                                                       

• An instruction is a form of control code, which supplies the information about an operation and the data on which the operation is to be performed.
• The control unit(CU) interprets each of these instructions and generates respective control signals.
• REGISTERS :- Resisters is a special storage area where data is held.

                              Register size refers to the amount of information that can be held in a register at a time for processing.

• The Arithmetic Logic Unit(ALU) performs the arithmetic and logical operations in Registers.
• An Input/Output system allows data input and reportinng of the results in proper format and form.
• For transfer of information, computer needs a internal system Interconnection. One such is BUS Interconnection.
• Main memory is needed in a comp8ter to store instructions an the data at the time of program execution.
• The memory unit stores all the information in a group of memory cells, called memory location , as binary digits.
• The contents of the desired memory locations are provided to the central processing unit by referring to the address of the memory location.

      

KEY FEATURES OF VON NEUMANN MACHINE :--  

1. The Von Neumann machine uses stored pogram concept that is program and data are stored in same memory.
2. Each location of the memory unit can be addressed independtly.
3.  Execution of Instruction is in sequential order, from one instruction to the next.
